I run a home server under Centos 7 and squid 3.5.20. The config is still work in progress as I started only today. Any tipps&tricks are welcomed The function is as expected when working from my LAN. But when I tested today from my cell phone from outside I received a few TCP_DENIED for web pages that are not part of the blacklists and I can access from my LAN. I also tried a few apps (e.g. Twitter, Linkedin, etc..) and none worked. Underneath the config as-is.
Any idea why I cannot connect? I have two more question I fiddled with and has no success: - Is there a possibility to re-direct certain MACs from the LAN through Squid and others can go direct? - Is there a good howto that describes in detail how autdetect proxy works with wpad.dat. I want that when users are on LAN they go through squid, but when they are travelling they can go direct.
